I agree with the person who said "Commonly White in an RV is ground" however the key word in that phrase is "Commonly"
And normally only one wire connects to the battery negative, This wire also connects to the frame and all other ground connections are made to the frame.
So any "extra wires" are usually positive.
And of course this helps not at all
Find out if anything does not work,, Jacks, Brakes (Break away, if it is a trailer for sure one of those leads is the brakes) and such... Meter the leads, see if there is 12 volt on them when plugged in.
From there you may get a clue.. When you find out label them
once you get it all hooked up get a can of RED spray paint (Any size you like includign Testor's model paint) and spray the POSITIVE end of the battery, wires and all.. Then you will know next time.
